Eh, I see no reason to switch to a dumb phone, because I don’t think I’m that bad with my current phone. My main User profile on GrapheneOS is pretty minimal when it comes to apps, it’s mostly messaging, banking, navigation, workout and music (I should probably move Lemmy and Pixelfed to a different profile, but they both have pretty little potential for scrolling for too long since the new content is naturally limited).
The only game on this profile is the one I’m developing as a hobby project lol

All the annoying Apps (Secondary Email, Amazon, Aliexpress, Linkedin, Smartlife, Grocery store coupon apps etc) are banished to a secondary profile that has no permission to run in the background or send any notifications.
